Critic reviews for Infected

We might get cranky over how dumb these people tend to be about their safety, but that's because we're rooting for them to survive.

[The creators] have managed to make Rick, Carl, Michonne, and even Beth all more worthy of the audience's consideration by underlining how their collective experience has made them hesitant to become emotionally invested in anyone or anything.

We had the creepiness of zombies in prison showers and wandering the halls of Cell Block D. We had a tearful goodbye to dad (we hardly knew you).

"Infected" was another successful episode in this rejuvenated (albeit young) fourth season, just different enough from The Walking Dead's raw formula to make the show feel new again.

Welcome to episode 2 of the fourth season where everything is terrible and the points don't matter! The Walkers scare me to no end, but this mysterious traitor is even more sinister.

Minor complaints aside, "Infected" achieves the difficult balance of traversing various narrative threads while maintaining a powerful emotional focus.
